IMPROVEMENT IN MOTORS FOR MACHINERY.

Specification forming part of Letters Patent No. 213,797, dated April 1,1879; application filed February 7, 1879.

To all whom it may concern:

Be it known that we, JOSEPH WILLIAMS, of Sharpsburg, EDGAR SMITH, ofPittsburg, and JOSEPH R. MILLIGAN, of Wilkins township, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Motors for Machinery; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawin g, and to the letters of referencemarked thereon.

Our joint invention consists, first, in the mixture, hereinafterdescribed, to be used for actuating a piston, consisting of the vapor ofbisulphide of carbon and petroleum oil; second, in the method,hereinafter described, for producing a motor for actuating a pistonviz.,injecting bisulphide of carbon into a boiler supplied with petroleum-oilpreviously heated; and,.third, in the method of operating apiston, ashereinafter describedviz., supplying the cylinder with a mixturecomposed of the vapor of bisulphide of carbon and petroleum-oil and witha small quantity of liquid petroleum-oil.

To enable others skilled in the art with which our invention is mostnearly connected to make and use it, we will proceed to describe itsconstruction and operation.

In the accompanying drawing, which forms part of our specification, Arepresents a furnace; B, a steam-boiler; O, a condenser; D, a forcepump, which is "connected with the boiler B and condenser O by pipes eand f, all of which are of the ordinary form and construction, theoperation of which is well understood.

We connect the boiler with the cylinder of an engine by a pipe furnishedwith the usual throttle-valve.

The boiler B is supplied with petroleum-oil or petroleum-oil and water,(preference being petroleum-oil,) filling the boiler to the ordinarywater-line. The lighter or volatile portion of the petroleum-oil must beevaporatedfor the purpose of separating the gasoline andbenzole from itprior to putting the petroleum-oil in the boilerB. We then heat thepetroleum-oil, or the petroleum-oil and water, in the boiler B to about200 of heat, which should be indicated by a suitable instrument. We thencharge the chamber 9 of the condenser C with bisulphide of carbon, thenopen the valve 71, so that the bisulphide of carbon will be forced bythe pump D gradually into the boiler B, which, coming in contact withthe previouslyheated petroleum-oil, or petroleum-oil and water, israpidly vaporized, forming a force or pressure in proportion to thequantity of bisulphide of carbon injected into the boiler, and the heatapplied thereto.

The boiler B should be provided With a suitable pressure-gage forindicating the pressure in the boiler, which will also enable theoperator to adjust the flow of the bisulphide of carbon.

The desired pressure being obtained, the vapor is allowed to passthrough pipe 2' to the cylinder of the engine for the purpose ofactuatin g its piston, the exhaust of the engine communicating by meansof the pipe j with the chamber K of the condenser G. The exhausted vaporfrom the cylinder of the engine being condensed is carried back againinto the boiler B, through the medium of the pipes e f and pump D, andworked over.

The cylinder of the engine must be supplied internally with a smallquantity of petroleumoil; also, the steam-chest and its valve or valvesand the piston-rod lubricated with said oil.

A motor, formed by bringing bisulphide of carbon in contact withpetroleum-oil, or petroleum-oil and water, as hereinbefore stated, will,with a small quantity of said oil in the cylinder of the engine, operatein all respects the engine as well as steam, with the cost of theformer, as compared with the latter, reduced atleast seventy-five percent, and is equally as well controlled by the engineer as steam.

The petroleum-oil is used for vaporizing the bi sulphide of carbon, forthe reason that it rapidly absorbs the heat of the fire, and therebyrapidly vaporizes the bisulphide of carbon, the evolving of whichatomizes a portion of the petroleum-oil, which atoms commin gle with thevapor, so that the latter acts as a lubricant in the actuating of thepiston for operating machinery.

We are aware that bisulphideof-carbon gas has been experimented with foramotive power in a great variety of ways, one example of which may befound in the English patent granted to A. V. Newton, No. 2,388, datedOctober 11,A. D. 1856. Our invention or discovery, in oontradistinetionto that of the said Newton, will more fully appear by a reference to hisalleged invention, as described in his specification, to which we makespecial reference, and for the reason that we wish it distinctlyunderstood that we do not claim, broadly, vaporizing bisulphide ofcarbon for a motor or vaporizing it by water, fatty oils, or glycerine.

Having thus described our joint invention, what we claim is- 1. Themixture described, to be used for
